Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents. We cannot ship your order until we receive the VIN.
Is this part truly ‘plug and play’?
Our VIN programming handles the main engine and transmission operating software. However, on many GM vehicles, you may need to perform a simple Security Relearn procedure after installation so the ECM can recognize your specific keys. This procedure can typically be done without special tools and instructions can be found online or in a service manual. In some cases, a Crankshaft Variation Relearn (CASE Relearn) may be needed with a scan tool for optimal performance.
Will this fix my transmission shifting problems?
In many GM vehicles, the ECM also controls transmission functions (sometimes called a Powertrain Control Module or PCM). If your shifting issues are caused by faulty electronic signals or logic from the computer, this replacement module can absolutely solve them. However, it will not fix internal mechanical failures within the transmission itself.
What if my original part number isn’t 19210737?
That’s okay. This ECM is the correct, updated replacement for several older service numbers. As long as your vehicle’s year, make, model, and engine are on the compatibility list, and your original part number is one of the listed interchangeable numbers (like 12590032, 12602044, etc.), this unit will work perfectly once programmed to your VIN.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a proper diagnosis performed. This includes checking for power and ground at the ECM connector and ensuring the communication network is intact. A professional mechanic can confirm the ECM is the root cause before you order a replacement.
